The following section describes how to register for the DC FUEL application. 

2.1 CDX Registration

The OTAQ DC FUEL system is hosted by the Central Data Exchange (CDX). CDX is the 

system that EPA has provided to all programs to standardize and centralize the reporting 

functions and data submissions that are required of the various EPA regulated communities. In 

order to access DC FUEL, users must first be registered users of CDX.

Registration for the OTAQDCFUEL: OTAQ DCFUEL Application dataflow is open to all CDX 

users. If you are an existing CDX user please refer to Section 2.3. 

2.2 DC FUEL Registration for New CDX Users

If you do not have an existing CDX user account please go to the following URL and complete 

your CDX Registration: http://epacdx.net/regwarning.asp?Referer=registration. 

If you are an existing CDX user please refer to Section 2.3. 

Users will reach the Terms and Conditions page upon accessing CDX Registration from the 

provided link, as seen in Figure 2-1. 

Figure 2-1 Terms and Conditions

Figure 2-8 Proceed to Verification

This page will provide you with two options: (1) use LexisNexis Identity Proofing to 

electronically validate your identity, allowing you to electronically sign an Electronic Signature 

Agreement (ESA) or (2) move forward to print, sign and mail in a paper ESA. 

Section 2.2.1 will take you through the process of completing LexisNexis and electronically 

signing your ESA. 

Section 2.2.2 will take you through the process of printing, signing and mailing in your paper 

ESA.

2.2.1 LexisNexis Verification

This section will take you through the registration steps if you choose to use the LexisNexis 

Identity Proofing process. 

If you choose to proceed with LexisNexis you will need to review all of the information provided 

on the Identity Verification page as seen in Figure 2-8 above. After you have reviewed the 

information and verified your first and last name, check the checkbox and click the “Proceed to 

Verification” button. 

LexisNexis Identity Proofing will be completed in a separate pop-up window. The first page will 

display an acknowledgement statement. Click the “OK” button. The next screen will require you 

to enter personal information. Figure 2-9 displays the LexisNexis verification pop-up window 

and required fields.

proofed by LexisNexis you will be taken to the Electronic Signature Agreement page to print, 

sign, and mail your ESA (see Section 2.2.2).

Note: The LexisNexis popup window will pre-populate your first and last name with the information entered 

during core registration. These fields will be read-only. 
Office of Transportation and Air Quality DC FUEL User Guide September 13, 2013

In some cases, you may be eligible to retry LexisNexis validation. If you are eligible for this 

retry you will be taken to the Retry LexisNexis page where you can launch the popup window 

once again. You will also be presented with the opportunity to verify or edit your first name, as 

shown in Figure 2-11. The opportunity to edit your first name will only be presented to you as 

long as you do not have another CDX role with a status of “Awaiting ESA.” At this point you 

may also choose to opt-out of the LexisNexis identity proofing by clicking the “Sign Paper 

Form” button. 

Figure 2-11 Retry LexisNexis

Click the “Retry LexisNexis” button. You will then be returned to the Identity Verification Page 

seen in Figure 2-8, and may begin your verification again. LexisNexis retries may be attempted 

up to five times before the identity proofing will be considered unsuccessful.

As previously stated, the OTAQReg dataflow is automatically listed in your CDX account upon 

registering for the DC FUEL application (if you are not already an existing OTAQReg user). It is 

required that you have an active user profile and company association with the Submitter role in

OTAQReg prior to being able to submit reports for your company in the DC FUEL application. 

In addition, OTAQ must have received your signed Electronic Signature Agreement (provided

3 DC FUEL Access

3.1 Activation of your Role

In order to access the DC FUEL application and submit reports, the OTAQ Program must 

activate your role in CDX. OTAQ is notified of your registration request once you successfully 

complete registration for the DC FUEL application (see Sections 2.2 and 2.3). OTAQ will either 

activate or deny your DC FUEL access pending receipt of your Electronic Signature Agreement 

and review of your OTAQReg registration. 

The “OTAQDCFUEL: OTAQ DC FUEL Application” dataflow link will not appear as clickable

until your role is activated by the OTAQ Program. 

Once your role is activated, you will receive an e-mail notification with the subject “CDX 

Registration Status Change” confirming that your registration status has changed. 

3.2 Access DC FUEL Dataflow 

Congratulations! The “OTAQDCFUEL: OTAQ DC FUEL Application” dataflow should now 

appear on your MyCDX home page. You may now access the OTAQ DC FUEL application and 

submit reports to EPA.
